What is the dimensions of the car? The wheelbase ?
I may have a body I can send you.

Took it for another run yesterday, but still found it very bouncy, so today I've been workingon moving the motor towards the rear a bit to ge more traction.
Pics to come of that, but here's the vid from yesterday.

Seems I'm behind with the updates here.
Moved the motor to the rear for more grip
Been playing around a bit with the steering configuration and the other day I threw a stringline over the steering knuckles to the rear axle to find the Ackermann angle.
Not 100% accurate as usual but it sure made a difference!
This car still needs suspension before it can be driven at top speed though.
Tucked the receiver in to a little box.
Once I find a good battery setup I'll have everything in one spot.
Receiver, switches and batteries.
Am looking at using some laptop batteries but need to get a voltage regulator first.
The batteries are a bit bigger than AA batteries and hold 3.7V each.
If you crack open a laptop battery there's 6 or 8 of these inside.
(Most large batteries contain smaller batteries.)
I'm holding a normal AA battery in this pic for size reference.
Also made a very crude but effective camera mount for the transmitter so I can film while driving.

Video of the new steering.
The second half of the video was shot with the transmitter mounted camera.
